CelFCC™

Unlike other wireless services, such as cellular and PCS, that have exclusive spectrum designated to them, MMDS services have to share the spectrum with existing users, commonly referred to as “incumbents.” Compliance with FCC regulations documented in FCCI documents (Appendix D), makes the design of MMDS network particularly complex because designers must account not only for intra-system interference but also for intersystem interference.

CelPlan^® has stepped forward and created CelFCC™ to provide operators with a tool that can fully and easily implement all the analysis required by the FCC.

CelFCC™ is an exceptional software tool designed to assist in the design and analysis of MMDS networks, providing a full implementation of all requirements set forth by the FCC for eliminating interference between incumbents and new entrants. This tool provides a one-button solution for the generation of the information required for MMDS and ITFS system filings.

The degree of complexity and detail for interference analysis of an MMDS project creates a computational dilemma for designers. For instance, calculations for one Response Service Area (RSA), depending on the size of the geographic region, can fall on the order of 3.6 billion calculations for just one interference prediction. Keeping in mind that in-depth system analysis may entail simulation of hundreds of interference predictions, without a comprehensive software tool to speed the analysis process, system designers would be at a loss for designing an efficient system that fully complies with all FCC requirements.

CelFCC™ solves this problem by providing designers with accurate interference analysis and computational efficiency. CelFCC™ provides the software engine for analyzing each geographical study point and accounting for intra-system interference between all cell sites within an MMDS system as well as the points that overlap an incumbent region. CelFCC™ also accounts for sectorization of sites as well as channels per sector relieving the system designers of the burden of performing these calculations by some other means. Designers should also recall that the FCC requires that every change to an existing MMDS system will entail additional interference analysis. With the competing objectives of system optimization on one hand and FCC compliance on the other, designers can rely on CelFCC™ to exponentially relieve this burden.
